• Face mask — In resuscitation and for minor methods underneath anaesthesia, a face mask is often sufficient to achieve a seal towards air leakage. Airway patency of the subconscious patient is maintained either with the aid of manipulation of the jaw or by the use of nasopharyngeal or oropharyngeal airway. These are designed to provide a passage of air to the pharynx thru the nose or mouth, respectively. Poorly geared up mask regularly reason nasal bridge ulcers, a trouble for some patients. Face mask are also used for non-invasive ventilation in conscious patients. A full-face mask does now not, however, offer protection towards aspiration. Non-invasive ventilation may be taken into consideration for epidemics of COVID-19 in which enough invasive air flow ability is not to be had (or in some milder instances), however pressurized protection suits for caregivers are advocated because of the risks of poorly fitting mask emitting contaminating aerosols.

• Tracheal intubation is often carried out for mechanical air flow of hours to weeks period. A tube is inserted through the nostril (nasotracheal intubation) or mouth (orotracheal intubation) and advanced into the trachea. In maximum cases, tubes with inflatable cuffs are used for protection in opposition to leakage and aspiration. Intubation with a cuffed tube is thought to provide the high-quality protection in opposition to aspiration. Tracheal tubes unavoidably purpose pain and coughing. Therefore, until a patient is subconscious or anaesthetized for different motives, sedative capsules are commonly given to provide tolerance of the tube. Other disadvantages of tracheal intubation include harm to the mucosal lining of the nasopharynx or oropharynx and subglottic stenosis.

• Supraglottic airway — a supraglottic airway (SGA) is any airway device this is seated above and out of doors the trachea, as an opportunity to endotracheal intubation. Most gadgets work via mask or cuffs that inflate to isolate the trachea for oxygen delivery. Newer gadgets characteristic esophageal ports for suctioning or ports for tube trade to allow intubation. Supraglottic airways vary usually from tracheal intubation in that they do not prevent aspiration. After the creation of the laryngeal mask airway (LMA) in 1998, supraglottic airway gadgets have emerge as mainstream in each non-compulsory and emergency anesthesia. There are many sorts of SGAs to be had such as the esophageal-tracheal combitube (ETC), laryngeal tube (LT), and the out of date esophageal obturator airway (EOA).

• Cricothyrotomy — Patients requiring emergency airway management, in whom tracheal intubation has been unsuccessful, may additionally require an airway inserted via a surgical opening within the cricothyroid membrane. This is much like a tracheostomy however a cricothyrotomy is reserved for emergency get entry to.

• Tracheostomy — When patients require mechanical ventilation for several weeks, a tracheostomy may additionally provide the most suitable get right of entry to to the trachea. A tracheostomy is a surgically created passage into the trachea. Tracheostomy tubes are well tolerated and frequently do no longer necessitate any use of sedative capsules. Tracheostomy tubes may be inserted early during treatment in sufferers with pre-existing excessive respiratory disorder, or in any affected person expected to be hard to wean from mechanical air flow, i.E., sufferers with little muscular reserve.

• Mouthpiece — Less common interface, does no longer offer safety towards aspiration. There are lipseal mouthpieces with flanges to help keep them in region if affected person is unable.
